The SRR1280A-331K is a shielded surface-mount power inductor from Bourns' SRR1280 series designed for input/output filtering in DC/DC converters and power supply applications. It features an inductance of 330 µH with ±10% tolerance, an RMS current rating of 1.10 A, and a saturation current of 1.40 A, with a DC resistance of 600 mO. The inductor operates at a self-resonant frequency of 2.9 MHz and exhibits a quality factor (Q) of 18 at 0.796 MHz, providing efficient energy storage and filtering. Its ferrite core construction with enameled copper wire and RoHS-compliant design make it suitable for portable communication equipment, camcorders, LCD televisions, and other compact power management systems requiring reliable high-inductance filtering.
